Data breaches and hacks are growing in frequency and scale. Any company that processes customer names, e-mail addresses, or payment information can be a target. Here are some major data breaches from recent years, organized by when the breach was uncovered:

Heartbleed (April 2014) – Internet users with accounts at websites that rely on OpenSSL encryption technology — including Yahoo, Pinterest and Instragram, among many others — were at risk of a data breach due to the Heartbleed bug. The coding loophole went undetected for two years, and it’s unclear exactly how many people exploited the vulnerability — and how many fell victim to it.

Neiman Marcus (January 2014) – A three-month attack targeted at least 350,000 customers. Payment information was potentially visible to hackers who infiltrated the system using malware. There is no indication that Social Security numbers or birth dates were compromised.

Adobe (October 2013) – Hackers illegally accessed the source code for a series of Adobe products. Thieves stole nearly 3 million encrypted credit card records and the company sent at least 38 million users notification to reset their passwords, according to Krebs on Security.

Multiple companies (July 2013) – Four Russian nationals and a Ukrainian man face charges for allegedly penetrating more than a dozen major corporations including Nasdaq, 7-Eleven, J.C. Penney and Heartland Payment Systems and stealing at least 160 million credit card and debit card numbers over a seven-year period.

LivingSocial (April 2013) – More than 50 million LivingSocial users were told to reset their passwords after a cyber-attack resulted in unauthorized access to user names, e-mail addresses, date of birth, and encrypted passwords. Thieves did not acquire credit card information, according to the company.

Evernote (March 2013) – The company reset passwords for about 50 million clients after hackers stole user names, associated e-mail addresses, and encrypted passwords. There is no evidence that thieves gained access to payment information for Evernote Premium or Evernote Business customers, according to the company. Pictured: Evernote CEO Phil Libin
